SDC2130 Performance

7 years 10 months ago #29527489 by motionEng
The SDC2130 is responding slowly to power commands. For example if it’s running at +100% then changed to -100% the step response time is slow. The response time is in the order of about 100ms or more. I can actually see this using my scope while monitoring the PWM waveform. This is going to cause problems for me. I need to speed up the response time.
Does anyone have any idea how to get the controller to respond faster?


Note: The contoller is set to open loop.

check the acceleration and deceleraton parameters.

The value is in RPM/s but this is converted in a \"Time to max\". This time is in referece to the MaxRPM parameter. The default values are 1000 for max RPM, and 2000 for the acceleration and deceleration, meaning 500ms from 0 to max PWM.
